Answer:
100 texts
Step-by-step explanation:
Let the amount of text messages be x. Since we are looking at making both plans equal, we add the fixed monthly charges to the number of messages multiplied by the cost.
The total amount charged by Totally will be 30 + 0.2x
The total amount charged by Gnarly will be
40 + 0.1x
Now since we are trying to get the number of text messages that make both charges equal, we equate the two charges and that is:
30 + 0.2x = 40 + 0.1x
40 - 30 = 0.2x - 0.1x
0.1x = 10
x = 10/0.1 = 100 texts
Answer:
x=9
Step-by-step explanation:
The two labelled angles are equal, so we can construct an equation. Then, we solve the equation for x.
First, we subtract 4x from both sides. Next, we add 25 to both sides. Finally, we divide both sides by 3.
Answer:
Susie made the error when she subtracted 2.
Answer:
True
Step-by-step explanation:
Since the rule is (x, y) ---> (x - 3, y - 4), you would subtract 3 from 0 (the x value of A) which would be -3. Then subtract 4 from 7 (the y value of A), which would be 3. So the answer would be true, that A' would be (-3, 3).
